Determining complexity for recursive functions (Big O notation)
...O notation, for each function:
int recursiveFun1(int n)
{
if (n <= 0)
return 1;
else
return 1 + recursiveFun1(n-1);
}
This function is being called recursively n times before reaching the base case so its O(n), often called linear.
int recursiveFun2(int n)
{
if (n &...
